REVERSING MECHANISM FOR WASHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 708,444, dated September 2, 1902.

Application filed October 26, 1901. Serial No. 80,102. (No model.)

To all whom, it may concern:

Be it known that I, DAVID B. \VILLOCK, a citizen of theUnited States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Reversing Mechanism for Washing-Machines; and I do hereby declare the following to be a full, clear, and exact description of. the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in motors for washing-machines, more particularly as required in laundries.

It has for its object, among other things, principally to dispense with the use of beltpower or belting, two belts, one crossed, being usually employed for obtaining the requisite movement of theoperative parts in effecting the washing aotion,which belts are greatly objectionable, notably because of uncertainty of action, dirt-producing, 850., while all pulleys, shafts, 650., therefor are accordingly omitted.

It consists, primarily, of actuating and reversing mechanism for the main driving gear or shaft of the operative parts of the washing-machine and of the detailed construction, arrangement, and combination of parts, substantiallyas hereinafter more fully disclosed, and specifically pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure l is a side view. Fig. 2 is a horizontal section, partly in plan. Fig. 3 is adetailed view more particularly of the cam mechanism between the beveled gear and the clutch mechanism. Fig. 4 is a section taken through Fig. 2 on the line 0000. Fig. 5 is a section taken on the line y y of Fig. 2. Fig. 6 is a section taken on the line a a of Fig. 2. Fig. '7 is a broken detached view more especially of the key or clamp and adjusting or holding screw and spring of the clutch or coupling.

\ or gear-wheels 2 2, with their cogs opposed to each other and having sleeves or hubs at their central outer ends, through which passes a common shaft 3. Said shaft is suitably mounted in position at one end, preferably upon castings or arms 3 3*, one bolted at its lower or inner end to a base or foundation piece, upon which is supported the motor proper, 4, the inner or higher end of said'casting or arm having a box bolted thereto to receive and constitute a suitable bearing for said end of said shaft. The opposite end of the shaft 3 is suitably supported or journaled in a boxing securely bolted to the part or casing 1 of the machine or apparatus, as seen in Fig. 2. The arm or support 3 haspreferably bolted to its lower end an additional support or arm 3, arranged at right angles thereto and suitably secured at its upper end to any convenient point, as shown. Said pinions or wheels have preferably their rims connected spider fashion or by arms or spokes 2 2 to their sleeves laterally of their radii, and each has an integral annular or circular portion 2, arranged or fitting Within which is a ring 5, the function of which will be presently apparent.

Upon the shaft 3, intermediately of the pinions 2 2 and suitably keyed to it, is a frictional hub 6, having lateral circular extensions 6 at its edges, occupying the space between said hub and said ring 5, said extension 6 being preferably elongated laterally at its outer edge or circumference to effect an extended area or surface of contact with said ring.

A circumferentially-grooved collar 7, having lateral flanges 7 preferably having outer beveled edges, is arranged upon the frictional hub 6 between its lateral circular portions 6 and has inserted transversely through it i a key or spline 7", providing for its turning with said hub keyed to the shaft 3, as before stated. Said key 7", adapted to haveendwise movement or to slide in its seat or way 7 in said hub and collar, is beveled or tapered at its ends, as at 7*, and is adapted to be alternately moved in either direction so as to be brought into action, as presently described, for either of the beveled wheels. Said rings have suitably connected thereto upon their inner circumferences stout plate-springs 8, one being applied to each ring, and through or in each plate or spring, near one end, is inserted and held firmly therein by jamnuts 8 a screw-bolt 9, preferably rounded at its engaging end, as more clearly shown in Fig. 7. It will be noted that as the splineor cam 7 is so moved, by accordingly moving the collar 7, as presently described, that one of said screw-bolts 9 shall be engaged by one of the beveled ends of said spline or cam,increased tension or stress will be imparted or transmitted to said spring accordingly, producing a binding action between the frictional hub 6, the shaft 3, and the rings 5, carried by the corresponding beveled pinion 2, thus frictionally coupling up said shaft and pinion. Simultaneously the key or cam 7" will thus be locked in position as against involuntary endwise movement or displacement.

Asmall beveled pinion 10, adapted to simultaneouslydrive or gear with the larger corresponding pinions or wheels 2, is carried by a shaft 10*, whose boxing is suitably supported by a branch arm 3 of the support or casting 3. Said shaft 1O has fixed to one end a right-line-toothed pinion 10, geared to the pinion 10 of the motor-shaft 10 thus providing for actuating the driving-pinion 10, imparting motion to the beveled pinion 2. It will be seen from thisarraugement that both of the beveled pinions 2 being driven by this same pinion 1O they are rendered capable of'receiving simultaneously a reverse movement-i. 6., being revolved in opposite directions at the same timethe motion of only one of which, however, being communicated at one time or operation to the shaft 3 and finally to the washing apparatus, as presently explained.

A bracket or arm 11, having a sleeve ll at one end inserted upon the tubular or cylindric portion 11 of the casting or support 3 and suitably fixed in position, has a stud or projection 11 extending laterally therefrom. Upon the stud or projection 11 is hung or mounted a Worm-wheel 12, meshing with a worm or screw 13, formed upon a sleeve 13, abutting the sleeve or hub of one of the beveled pinions 2 and suitably fixed to the shaft 3. Said worm-wheel 12 has a lateral rollequipped stud 14, and suitably hung from the arm or bracket 11, as at 11, is a peculiarlyconstructed cam 15, having lateral opposite inwardly-converted surfaces or faces 15, with which engages said roll-equipped stud of said Worm-wheel. An angular lever 16, carried by the cam 15, is pivoted toa disk 16, having a pivot upon its lower side bearing in a socket 16, cast or integral with the free end of the arm 11, and this lever has two or duplicate prongs or a shipper 16. These prongs have their inner ends embracing and connected to the hub-embracing collar 7 about centrally thereof in its peripheral or circumferential groove. Said cam 15 has a vertical enlongated slot 17, which receives a stud or pin 18, secured, as at 18, to the arm 11. A pinion 19, secured upon the opposite end of the shaft 3, is geared or meshed with the main driving gear-wheel 20, secured upon the shaft of the Washing apparatus or machine for actuating the last-named therethrough from the motor, as will be readily understood. It Will therefore be seen that as motion is transmitted to the gear wheels or pinions 2 by the moving of the pinion 10 into gear therewith, one of said gear-wheels having been previously shipped or moved so as to effect connection thereof with the shaft 3 by means of the frictional coupling or clutch, as before explained, rotation will be imparted to said shaft, which will continue to rotate a limited period, actuating through intermediate gearing, shafts, &c., the washing apparatus. During such operation or action of parts the shaft worm or screw '13 being in mesh with the worm-wheel 12 the last-named will be actuated, causing its roll-equipped stud 14 to engage one convexsurfaee or face 15 of the cam 15. Said cam will be shifted under this action, being free to conform to the obliquity of movement thus imparted thereto by reason of its elongated slot and pin or stud connection 17 18 and carry with it and so dispose the angular lever 16 as to accordingly deflect its shipper 16 correspondingly moving or sliding the collar 7, in turn carrying its key or cam 7 let into the frictional hub 6, laterally into engagement with the opposite beveled end of the screw-bolt 9. Said bolt yielding because of the flexibility of its suspending-spring 8 will permit the passage of said end of said key or cam thereunder, increasing the tension or stress of said spring and accordingly jamming the frictional hub 6, the ring 5, equipped with said spring and screw-bolt, and said key or cam between the gear-wheel 2 and shaft 3. This, it is obvious, effects the connecting or coupling together of the opposite or previously-uncoupled gearwheel and said shaft, starting the rotation of the shaft in the opposite direction, accordiugly effecting the reversal of the washing operation, all without the use of belting, &c., consequently avoiding the objections and disadvantages thereof, as above noted. Said action of parts will be repeated at intervals throughout such washing operation.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
